ONE STEP STRIP STYLE HAV IgM TEST (COLLOID GOLD)

INTRODUCTION

The one step strip style HAV IgM test is a rapid test based on the principle of immunoassay combined with conjugated colloid gold technology. The HAV test is a diagnostic device for qualitative detection of anti-HAV IgM in human serum (or plasma) specimen.

SUMMARY

In acute infection period, anti-HAV IgM is present of high level in the patient’s sera. The IgM antibody titer is decreased significantly and even disappeared in convalescence period, instead IgG is present. Since cases of hepatitis A are not clinically distinguishable from other types of acute viral hepatitis, a correct diagnosis can be made by blood tests which detect the specific anti-viral antibodies.

SPECIMEN COLLECTION

For serum（or plasma）, collect blood into a container without anticoagulant. If the specimen cannot be tested on the day of collection, store the serum (or plasma) specimen in a refrigerator or freezer. Bring the specimens to room temperature before testing.

TEST PROCEDURE

1. Dilute the serum (or plasma) specimen 1000 times with 0.85% NaCl solution.
2. To begin testing; open the sealed pouch by tearing along the notch.. Remove the test form the pouch.
3. Immerse the strip into the sample with the arrow end pointing towards the sample. Do not immerse past the MAX (maximum) line. Take the strip out after 3 seconds and lay the strip flat on a clean, dry, nonabsorbent surface
4. Wait for colored bands to appear. Read results within 10-15 minutes. Do not read results after 20 minutes.

INTERPRETATION OF RESULTS

Negative: Only one pink band appears on test region of the Strip. This indicates that there is no detectable anti-HAV IgM in the specimen.

Positive: Two pink bands appear on test region of the Strip. This indicates that the specimen contains detectable amount of anti-HAV IgM.

Invalid: If without colored band appears on test region, this is an indication of a possible error in performing the test. The test should be repeated using a new device.

PRECAUTION:

1、Must use fresh specimen and avoid repetitive freezing, the result will be invalid

2、Use it before expiry date.

3、The package of kit should not be opened until it reaches the room temperature if it taken out from the refrigerator. Use the test kit as soon as possible but within 1 hour after removal from pouch specially if the room temperature is more than 30℃ and in high humidity environment.

4、Old Serum can not be used. If the serum is thick, it can be used only after being separated.

LIMITATIONS

1、The test is for in-vitro diagnostic use only.

2、The test is qualitative filter detection，it can not be used as the final test for blood donor。

STORAGE AND STABILITY

The test kit can be stored at room temperature (2 to 30°C) in the sealed pouch to the date of expiration. The test kit should be kept away from direct sunlight, moisture and heat.
